I got a chance to send some 150gr Hornady RN down range with Trail Boss and my 308. It was a hoot! i tested loads from 11.0gr to 15.0gr. They were all plinking accurate and darn near POA at 50yds (100yds not so much). However, 13.0gr printed a .8in 3-shot group at 100yds, even if it was 3.5in low and right (rifle sighted at 200yds with 165's). This could be a good camp round or trainer for a youngster. There is very little recoil with velocity running at email@example.com to firstname.lastname@example.org. If you have some Trail Boss on your bench try some in you rifle, it will make you smile!
